Pasting across multiple clips and tracks

So, I guess that what I'm trying to build is a scritp that would keep pressing TAB within a specific time selection. It would keep tabing if a fade is found, and would only paste if a clip end is reached.
Any advice on how I would go about doing that?
Is there any way to investigate this for the non-coders like me?
Thanks!

Hello Facundo,
This will paste and fill selection on silence between clips on an initial selection, so far will do one track only.
Please copy to clipboard the audio you would like to paste, make a selection and run the script.

function getUserMainCounter() {

    // get current counter
    const mainCounter = sf.ui.proTools.getCurrentTimecode().stringValue

    let originalTimeCounter
    /// Bars Beats .  
    if (mainCounter.includes("|")) originalTimeCounter = "Bars|Beats"
    //  Min Secs .    
    else if (mainCounter.includes(":") && mainCounter.includes(".")) originalTimeCounter = "Min:Secs"
    //  Time code
    else if (mainCounter.split(":").length == 4) originalTimeCounter = "Timecode"
    //  Feet+Frames
    else if (mainCounter.includes("+")) originalTimeCounter = "Feet+Frames"
    //  Samples.     
    else originalTimeCounter = "Samples"

    return originalTimeCounter
};

    return nowSel.selectionStart <= initialSel.selectionEnd && nowSel.selectionEnd <= initialSel.selectionEnd
